摘要:
The invention provides a preparation method of high-content Ganoderma lucidum β-glucan and an efficient and rapid detection method thereof. The preparation method comprises ethanol-trypsin pretreatment of Ganoderma lucidum fruiting body in combination with ultrasonic-assisted alkaline hydrothermal extraction of β-glucan from Ganoderma lucidum, and purifying β-glucan by DEAE Sephadex A-25 Sephadex column chromatography using NAOH solution as a mobile phase, to obtain high purity (≥90%) of Ganoderma lucidum β-glucan. The detection method comprises placing the extracted β-glucan in an autoclave and performing hydrolysis with β-(1,3)-exo-glucanase and β-glucosidase, and detecting and analyzing the content of the prepared β-glucan by high pressure-acid enzymatic hydrolysis-HPLC method, using glucose as a standard. The preparation method of β-glucan has high extraction ratio. The efficient and rapid detection method has high sensitivity, high accuracy and good repeatability, and thus has a wide application prospect.

FIG. 1 is a perspective view of a heating stove, showing my new design; FIG. 2 is another perspective view thereof; FIG. 3 is a front view thereof; FIG. 4 is a rear view thereof; FIG. 5 is a left side view thereof; FIG. 6 is a right side view thereof; FIG. 7 is a top plan view thereof; FIG. 8 is a bottom plan view thereof; FIG. 9 is an enlarged view of portion of FIG. 1; and, FIG. 10 is another enlarged view of portion of FIG. 1. The dash-dash broken lines show portions of the heating stove and form no part of the claimed design. The dot-dash broken lines shown in FIGS. 1, 9 & 10 define the boundary of the enlargement area and form no part of the claimed design.
摘要:
A system for multi-scale closed-loop eye tracking to compensate for translation and rotation motion while imaging in vivo a surface area of an internal structure of an eye of a subject includes a narrow field imaging device optically coupled to an optical path to receive light reflected from the surface area of the structure of the eye. A wide field camera is optically coupled to the optical path by a beam splitter disposed in the optical path. A tracking mirror is disposed in the optical path between the beam splitter and the structure of the eye. A control process algorithm actively compensates substantially in real time for both translational and rotational movements of the eye. A system where a torsional correction device causes a rotating movement of a subject's head and a method for multi-scale closed-loop eye tracking are also described.
